Usage of i-save operation:
1.Using as a low-energy mode
i-save operation can be used as a low-energy mode by setting the temperature 2–3: warmer than the normal cooling
temperature or 2–3: cooler than the normal heating temperature. This is good to use if a room is unoccupied or while
you are sleeping.
■ Before leaving the room unoccupied:
• Press i-save button to switch to the low-energy mode before leaving the room.
• When you return to the room, the temperature will not be too hot or too cold.
• Press i-save button again and the air conditioner will operate with the normal settings for temperature, fan speed,
and air flow direction for a comfortable, air-conditioned environment.
■ Before sleeping:
• Before going to sleep, press i-save button, and then go to your bedroom.
• While you are sleeping, the room will be air-conditioned using the low-energy mode until the following morning.
• In the morning, press i-save button again, and the air conditioner will operate with the normal settings for tempera-
ture, fan speed, and air flow direction. The set room temperature will be obtained quicker than if the air conditioner was
stopped while you were sleeping.
2.Using as a mode for frequent settings
If you often switch between two groups of settings for temperature, fan speed, and air flow direction in the same operation
mode, save one group of settings using i-save button. This will allow you to select the desired group of settings simply
by pressing i-save button, avoiding the troublesome remote controller operations.
<SWING operation>
In swing operation of ECONO COOL operation mode, the initial air flow direction is adjusted to “Horizontal”.
According to the temperature of indoor coil thermistor RT12 at starting of this operation, next downward blow time is
decided. Then when the downward blow has been finished, next horizontal blow time is decided.
For initial 10 minutes the swing operation is performed in table G~H for quick cooling.
Also, after 10 minutes when the difference of set temperature and room temperature is more than 2:, the swing oper-
ation is performed in table D~H for more cooling.
The air conditioner repeats the swing operation in various cycle as follows.
